there should be no interference. The rest like trigger signals, etc. depends on your remaining software/hardware stack.

In addition to the 8 or 16 EEG channels, Cyton can record external device opto-isolated trigger channels, as 'aux input' channels. But Cyton has no OUTPUT trigger generation capability. This page show

* external trigger systems

* piezoelectric reflex hammer (trigger input)

... Sorry for the naive question, but can I do it without LSL, i.e. can triggers from an external software be directly sent to the Cyton board (for instance via the USB dongle)?

The Cyton external trigger pins are intended to be used with a source of DIGITAL input levels.

* Packet loss also appears when pressing the PROG button to generate a trigger (following this guide:

I am trying to run an experiment on PsychoPy while also recording EEG using the OpenBCI Cyton board. I would like to send triggers from the Psychopy experiment to the EEG recordings.

In the IEEE paper, I believe they mention LSL timestamps. These are less accurate and more finicky than the simple Cyton External Trigger mechanism I mentioned. As long as your subjects are in the sam

we introduce a novel wireless hardware-trigger synchronization approach based on sub-1GHz technology with a customized acquisition software, leveraging affordable commercial wireless EEG (OpenBCI Cyt

My suggestion would be to use one of your channels on each system as a 'sync' channel. Then supply low voltage timing marks to both systems on this channel. On Ganglion you would have to use an EEG ch

3. Trigger markers and event synchronization

* Predict emerging fatigue early (before the user consciously feels it) and trigger break notifications

So far, for ERP viualization, my EEG Data is maybe too bad because no accurate ERP image could be plotted. Even if the latencies of the trigger transmission are taken into account, which are about 0,0

At this moment, my setup consists of OpenBCI Gelfree BCI Cap + PsychToolbox visual trigger code + Emotibit. All streams synchronized via LSL and saved as an XDF File via LabRecorder. Emotibit is just

The best approach with P300 experiments, is to use the External Trigger capability of Cyton, to record a simultaneous time mark from the stimulation event, along with the actual EEG data stream. LSL m

As you can see from the graphs I inserted above, ERP signals are very weak, say from 5 to 10 microvolts. This is going to be lost in the noise unless you have tight synchronization with the onset of t

Unfortunately, I have already completed my measurements and do not have the opportunity to add an external trigger at this stage.

You should consider using the 'external trigger' feature of the Cyton. An optoisolator will disassociate your stimuli signal from the low voltage used by Cyton.

of on-screen 'buttons' that when gazed at, trigger the associated activity you have designed.
